Western Signal Blizzard Series

The Blizzard Series was a line of electromechanical sirens produced by Western Signal. It was basically Federal Signal's 500 Series made by Western Signal under license. It went through a lot of prototyping, ranging from a coded unit that allows it to make a "pulsed" signal, along with variants of single and dual tone models, even different phase motors were tested. They finally settled on one design that was compact, yet effective. This model unfortunately was advertised as a "mid-range" siren by Western Signal, which in turn caused their Whistler Series siren to outsell it by a long shot. The most powerful unit they made was the 8/12 port, 3-phase Blizzard 130.
